Let Rachel finish her show first

Remaining in place since you're enjoying the show too much to let it end just yet, you watch closely from behind how Rachel's index finger wiggles its way deeper into her cunt. Turning her wrist rhythmically and pumping it up and down, Rachel fingers herself for a little bit, then throws a quick glance down at your stiff cock. You give it one long, slow stroke, and Rachel licks her lips.

Soon, Rachel's finger slips back out of her cunt, and instead she latches onto her bubble butt with both hands. Leaning further forwards until one side of her face is placed against the wall, Rachel's new stance ensures that she manages to thrust her ass out even closer towards you. Your grip of your cock tightens and a low groan escapes your mouth at the sight of Rachel pulling her full, firm asscheeks wide apart, stretching her puckered, soap-covered asshole and showing it off for you.

With a naughty smile and a wink, Rachel's lets go of her right asscheek and slides her hand down across it, into her anal cleavage. Soap has caught onto all her fingers, and she's soon got her right index finger – which is also covered in her wetness – lined up against her bunghole. Again, she's shifting her wrist, rubbing her fingertip against her anus, and the two of you have your gazes meet before she smiles for a second or two, then has her smile transform into a lustful grimace as you watch her press her digit up tighter against her backdoor.

“Go on, Rachel,” you gently urge your gorgeous girlfriend, though it's unlikely she can hear you through the glass door and over the sound of the running water as it washes over her curvy form. Your hand is still wrapped round your cock, but you're not stroking it. Instead, you remain perfectly still, vaguely aware of how you've leaned in slightly to get a marginally closer look of Rachel's fingertip slowly opening up her tightest hole.

Eventually, after she applies just a tad more force, Rachel's finger opens up her sphincter, and its tip sinks in through it, prompting a lustful moan loud enough that you can easily pick up on it, and it prompts you to start jacking your cock with a few pumps before you catch yourself. As arousing as it is, Rachel's little show isn't going to make you waste your first cumshot of the day by having it be dumped onto the bathroom floor.

Looking back at you, Rachel pushes her finger deeper into her anal passage, pulls back, and then thrusts forwards, her eyes closing and her lips parting as she drives the sole digit as far past her bunghole as she can. She fingers her ass for another few long and extremely enjoyable moments, spearing her digit in and out through her ringpiece while sending you the kind of glances that tells you perfectly just how much she's enjoying having you there to watch her do it. While she's keeping herself busy, Rachel's gaze drifts down to your cock ever so often, and you finally reward her for turning you on like this by giving it another couple of pumps, although you're not moving your wrist, but rather your hips, thrusting them back and forth to make your hard member spear its way through your grasp.

“John!” Rachel cries out your name when she sees you masturbating, and the next thing that happens is that her left hand slips down in front of her, with you knowing perfectly well what it's going for. Then, just as she's wrapped her hand round her own stiff cock, Rachel lets go and starts wiggling her finger back out of her rosebud. Once she's done that, Rachel stands back up and soaks both hands with more shower gel.

Turning towards and stepping out of the spray of water, Rachel lets you see how she's as rock-hard as you before proceeding to turn around again. Pressing the index and middle fingers of your left hand together, you use them to make a pretty suggestive gesture, and Rachel smiles and nods to say that she understands.

Rachel's left hand is soon grabbing her left buttock, pulling it to the side once more, although this time around it's primarily for your viewing pleasure, as her right hand comes snaking in between her legs, Rachel having slipped it in beyond her balls before spearing it across her pussy and further on towards her anus.

With the small size of the shower meaning that her head and shoulders become immersed in the water raining down from above when she lean forwards, Rachel places her index and middle fingers against her bung and push upwards and forwards, her hips going through a quick little jerking motion when the digits make it through her sphincter.

In comparison with the first fingering, Rachel is going at a much higher pace this time around, and you watch through the increasing condensation of the glass door how she starts drilling the two digits deeper and deeper past her bung, little bubbles of soap washing lazily down her thighs as she closes her eyes and goes even faster.

Once she's gone from merely fingering her ass to finger-fucking it with steadily increasing relish, Rachel manages to send you another sultry glance moments before lunging for her dick with her left hand. This time around, she isn't satisfied with just fondling it for a few seconds, and as she straightens up and moves deeper into the shower, you can see her elbow bobbing back and forth as her hand races up and down her member.

You smile at how quickly Rachel reaches the point where she's jerking off in the same intense fashion that she's seesawing away at her ass, and sincerely doubt that she'll be able to stop herself. Naturally, the sight of your complete bombshell of a girlfriend masturbating frantically is an extremely arousing one, marred only by the growing condensation on the door obscuring your view slightly. In order to rectify that, you move in closer and open the door. Though Rachel coos at you doing so, she doesn't stop, and now you have an unrestricted view of her pumping those gel-coated fingers in and out of her ass and stroking her cock at the same time, her slow, irregular walk through the shower having brought her tits back into contact with the innermost wall while her juicy booty is back to being thrust towards you even as each thrust of her hand makes it all bounce and jiggle in a way that has you thinking about dropping down on your knees to thank everything that's holy for the gas leak at your gym that day.

“Fuck, John!” Rachel is way too horny to even try to look seductive when she glances back at you a few moments later, but the arousal that her pretty face is practically glowing with is more than enough to make you grunt and tug at your cock. When you do so, Rachel looks down at what's sticking out proudly from between your legs, moans, and speeds up her jerking of her own member.

“John!” With another cry of your name, Rachel starts pumping her hips, tossing them backwards and forwards as her fingers now settle down as far into her anal passage as she can get them and her other hand keeps working her slick, hard cock, still hidden from your view by her big, perfect booty.

“That's it,” You urge her on, softly, now that she can actually hear what you're saying without you having to raise your voice, “Cum for me, my naughty, gorgeous slut.”

“O-oh, oh God!” Another couple of moments later, Rachel's voice peaks as she slams her hips forwards and upwards, shoving her cock through her grasp one last time before you can tell from her expression, her tone and the way in which she's started to tremble that her orgasm has just arrived. Also, there's already a few streaks of jizz glued to the wall in front of her as she starts swaying from side to side and backwards and forwards while her orgasm rolls over her in pulses.

When she finally comes down from her first orgasm of the day, with her dick shooting out one last rope of cum onto the wall and the water coming from above not getting to the quite copious amount of her juices that has been glued to the inside of her thighs, Rachel sighs dreamily as she stumbles another step towards the wall and puts the hand that had been wrapped around her dick against it. Another moment later, and with another dreamy sigh, she pulls her fingers from her ass.

“That was fantastic, honey,” You say, prompting Rachel's loudest and dreamiest sigh thus far by stepping up behind her and wrapping your arms round her stomach as you push your hard cock against her back.

“T-thanks,” Rachel lets out a tired giggle as you kiss the side of her head, and then the energy fills back into her voice as you grind the underside of your cock against her spine and between her cheeks, “Feels like you enjoyed it too.”

“Definitely,” You lean in to meet Rachel in the first kiss of the day, one that has the two of you pressing your bodies closer together while your tongues meet.

“However...” Your right hand leaves the point where it'd been placed on top of your left against Rachel's stomach, and you use it to dismount the showerhead again, “I'm not sure you really did that good a job cleaning yourself up.”

“John...” Rachel whimpers with excitement as you take one step back.

“Spread your cheeks for me, Rachel,” You softly order your girlfriend, who eagerly complies, leaning forwards to press her huge boobs against the wall before grabbing onto her asscheeks with both hands and prying them apart.

“Oh fuck!” Rachel's voice is filled with excitement as you aim the showerhead straight at her asshole, though the spray is wide enough that you get to specks of water bounce off her buttocks as you keep trying to hit that puckered little bullseye between them dead-on.

“Just going to wash that soap away, honey,” You lie, and dip the spray lower, letting it hit her pussy from behind as you start rubbing your left thumb against her sphincter. Rachel just cries out in lust and pushes her bubble butt further towards you, although you refuse to let your thumb slip inside her backdoor.

“Naughty slut!” With a grin, you let the water hit her asshole again and land a playful slap on her ass with your left hand, which makes Rachel cry out even louder.

“Remember that time when you got so naughty I had to punish you with a spanking?” You ask, and rub your hand softly against her asscheek, kneading her firm flesh between your fingers.

“I got so horny...” Rachel admits, with her eyes closed tight and as her firm ass wiggles against your grasp.

“Yeah, I was kind of wondering how much longer you could have lasted,” Moving your left hand in closer to Rachel, you smile at her gasp when the showerhead is pressed against her bubble butt, and how she pulls her cheeks further apart to let the water wash over her bunghole.

“W-we'll have to find out, won't we?” Rachel's voice continues to break up every now and then, and you're sorely tempted to reach in and gauge how hard she's gotten.

“Uh-huh,” But you don't, and instead mount the showerhead back in its cradle, “But for now, I'm guessing that sexy little asshole of yours is clean enough to eat from...”

“John...” Since you just turned the water off, there's nothing there to obscure the excitement in Rachel's voice, and she's soon letting out a moan as you drop onto your haunches behind her.

“Look at that cute, teeny bunghole of yours,” You say with a grin after Rachel's pushed her ass even closer to your face, her buttocks still in her grasp and pulled apart for your benefit.

“Oh, fuck!” Rachel cries out when you let your hot breath wash over her backdoor, “Lick it, John! Get your horny girlfriend's ass ready for your big dick!”

Truth be told, her asshole is probably ready for you already after all the attention it's gotten so far, but that certainly doesn't stop you from leaning in closer and shoving out your tongue to have its tip connect with her bung.

“Yes!” Rachel gasps when you run the tip of your wet muscle along her sphincter, slowly coating it with your saliva. Of course, since she's got such a firm grip of her buttocks, you're free to prod her pussy with your fingers, and Rachel's soon unleashing one gasp after the other as you tease her wet, bald fuckhole with your fingertips while your tongue remains focused on her ringpiece.

You keep working Rachel's ass with your tongue for quite some time, with her moans getting louder and louder as she tries not to jerk about too much thanks to what you're doing, prodding her tight hole with the tip of your tongue and working it all over it, until you suddenly stop and pull back.

Rachel moans at you stopping what you've been doing for the last couple of minutes, but by the time you're back to standing behind her, she's got both hands against the wall and has pushed her ass out to meet you, with the result that your cock is snuggled in between her buttocks.

“Now,” You begin, as you reach in and wrap one hand round your girlfriend's hard, throbbing member, “Are you ready for your first assfuck of the day, my sexy, nympho slut?”
